Squeezed light is a useful phenomenon that can be exploited to improve the sensitivity of specific classes of detectors based on optomechanical effects. In this work, we clarified the effect of the squeezed light by explicitly presenting the role of squeezing parameters on the final effective temperature and effective quantum number of the oscillator. The results show that the cooling and heating effects are strongly dependent on the squeezing parameter and phase. The lowest effective temperature and quantum number of three orders of magnitude smaller than that in the case of no squeezing can be obtained. The study gives important information for optimizing the cooling efficiency with squeezed light.
